1. Microfluidic-Enabled of Liposomes Elucidate Size-Dependent Transdermal Transport
Topic: Drugs/Pharmaceuticals
Published: 3/21/2014
Authors: Wyatt N Vreeland, Renee R Hood, Eric Kendall, Don L. DeVoe, Julia Finkel, Mariana Junqueira, Zenaide Quezado
Abstract: Microfluidic synthesis of small and nearly-monodisperse liposomes is used to investigate the size-dependent passive transdermal transport of nanoscale lipid vesicles. While large liposomes with diameters above 105 nm are found to be excluded from dee ...

2. Facile Smiles-type rearrangement in radical cations of N-acyl arylsulfonamides and analogs
Topic: Drugs/Pharmaceuticals
Published: 1/21/2014
Authors: Karl K Irikura, Nino Guram Todua
Abstract: RATIONALE: N-Alkylation of sulfonylbenzamides was reported recently to cause a dramatic and surprising change in electron ionization mass spectrometry (EIMS), leading to a closed-shell base peak. Only an incomplete, speculative mechanism was availabl ...

3. Microfluidic preparation of liposomes to determine particle size influence on cellular uptake mechanisms
Topic: Drugs/Pharmaceuticals
Published: 10/3/2013
Authors: Wyatt N Vreeland, Abhay U Andar, Renee R Hood, Don L. DeVoe, Peter W Swaan
Abstract: Purpose: This study investigates the cellular uptake and trafficking of liposomes in Caco-2 cells, using vesicles with distinct average diameters ranging from 40 nm-276 nm. Liposomes were prepared by microfluidic hydrodynamic flow focusing, producing ...

4. TLR stimulation initiates a CD39-based autoregulatory mechanism that limits macrophage inflammatory responses
Topic: Drugs/Pharmaceuticals
Published: 9/12/2013
Authors: John P Marino, Katharine Therese Briggs, Heather Cohen, Katya Ravid, Simon C. Robson, David M. Mosser
Abstract: Sepsis is a highly fatal disease caused by an initial hyperinflammatory response followed by a state of profound immunosuppression. Although it is well appreciated that the initial production of proinflammatory cytokines by macrophages accompanies th ...

5. Microfluidic Synthesis of Nano-Liposomal Anesthetics
Topic: Drugs/Pharmaceuticals
Published: 5/12/2013
Authors: Wyatt N Vreeland, Renee R Hood, Eric Kendall, Mariana Junqueira, Julia Finkel, Don L. DeVoe
Abstract: Topical anesthesia has the ability to provide painless application of pain management medications for minor procedures such as venipuncture, particularly in the pediatric population. Liposomes have been proposed as a highly advantageous nanocarrier f ...

6. Quantitative Analysis of Dendron-Conjugated Cisplatin-Complexed Gold Nanoparticles Using Scanning Particle Mobility Mass Spectrometry
Topic: Drugs/Pharmaceuticals
Published: 5/8/2013
Authors: De-Hao D. Tsai, Tae Joon Cho, Sherrie R. Elzey, Julien C. Gigault, Vincent A Hackley
Abstract: We report a high-resolution and traceable method to quantify the drug loading on nanoparticle-based cancer therapeutics, and demonstrate this method using a model cisplatin functionalized dendron-gold nanoparticle (AuNP) conjugate. Electrospray diffe ...

7. The Metrology of Counting Protein Particles
Topic: Drugs/Pharmaceuticals
Published: 3/18/2013
Authors: Dean C Ripple, Michael J Carrier, Richard E Cavicchi, Christopher B Montgomery, Zhishang Hu
Abstract: A common degradation pathway for protein-based drugs is the growth of protein aggregates or particles. Counting and characterization of these particles is needed to assure the quality, efficacy, and safety of this type of drug. The unusual physical ...

8. Modification of tethered bilayers by phospholipid exchange with vesicles
Topic: Drugs/Pharmaceuticals
Published: 2/27/2013
Authors: David J Vanderah, Rima Budvytyte, Mindaugas Mickevicius, Gintaras Valincius, Frank Heinrich
Abstract: Phosphatidylcholine and cholesterol exchange between vesicles and planar tethered bilayer lipid membranes (tBLMs) was demonstrated from electrochemical impedance spectroscopy (EIS), fluorescence microscopy (FM), and neutron reflectometry (NR) data. ...

9. Breast Cancer Biomarker Measurements and Standards
Topic: Drugs/Pharmaceuticals
Published: 1/24/2013
Authors: Kenneth D Cole, Lili Wang, Hua-Jun He
Abstract: Cancer is a heterogeneous disease characterized by changes in the levels and activities of important cellular proteins, including oncogenes and tumor suppressors. Genetic mutations cause changes in protein activity and protein expression levels that ...
